Along more than a decade, R&D on supercritical fluid extraction (SFE) of vegetable matrices
has been increasingly reported in the literature. Aiming at portraying the current state of this …

Supercritical fluid extraction (SFE) of plant material with solvents like CO2, propane, butane,
or ethylene is a topic of growing interest. SFE allows the processing of plant material at low …

Ursolic acid (UA) is a pentacyclic triterpenoid widely found in herbs, leaves, flowers and
fruits; update information on the major natural sources or agro-industrial wastes is …

This work addresses scientific and techno-economic aspects of supercritical fluid extraction
(SFE) of spent coffee grounds which are of interest under the biorefinery context. Soxhlet …

The aim of this study was to investigate the possibility of isolating bioactive phenolics
compounds from spruce bark (Picea abies), using sub-and supercritical fluids. In order to …

The pulp and paper industry is recognized as a well-established sector, which throughout its
process, generates a vast amount of waste streams with the capacity to be valorized …

Extracts of Eucalyptus globulus leaves were produced and characterized aiming their
enrichment in natural bioactive compounds such as triterpenic acids (TTAs). Soxhlet …

Micrococcus flavus and Pseudomonas aeruginosa. The bacterium most sensitive to the
extracts was Escherichia coli, whereas the most resistant was M. flavus. 13-epimanool and α …

The supercritical CO2 extraction of E. globulus deciduous bark was carried out at different
temperatures (40–60° C), pressures (100–200bar), and ethanol contents (0.0–5.0 wt.%) to …

Eucalyptus bark contains significant amounts of triterpenoids with demonstrated bioactivity,
namely triterpenic acids and their acetyl derivatives (ursolic, betulinic, oleanolic, betulonic, 3 …
